Uh... AFAIK, MzScheme never supported "structured" LAMBDAs or
DEFINEs, e.g.:

    mz> (define ((foo x) y)
	  (+ x y))
    define: bad identifier at: (foo x) in: (define ((foo x) y) (+ x y))
    mz>

But even a very old Elk-3.0 seems to:

    elk> (define ((foo x) y)
	   (+ x y))
    foo
    elk> (foo 37)
    #[compound value]
    elk> ((foo 37) 3)
    40
    elk>
